A grieving mum will soon learn the facts behind her son's drug death while in police custody.

The lengthy investigation into Martin Dakers' death, more than a year ago, has been completed and a copy is now due to be sent to his mother Marie.

The move comes three months after a man was jailed for supplying Ecstasy tablets to Martin, 17, and two 15-year-olds.

Mrs Dakers, 36, has confirmation from the Independent Police Complaints Commission (IPCC) which supervised the inquiry into her son's death, that it has been completed.

At her home in Pendle Close, Lambton Village, Washington, Mrs Dakers, who has two daughters, said: "I'm pleased that at last we are getting somewhere. At least this report will provide some answers to my questions about Martin's death. But there's the inquest on Martin to come yet."

Martin was arrested at 9pm on March 14, 2003, and taken to Washington Police Station, in The Galleries. Ninety minutes later he was found unconscious in a police cell. He died at Sunderland Royal Hospital.

Post mortem tests showed he had a heart attack, after taking Ecstasy tablets before he was arrested.

This March Christopher Hartshorn, 20, was jailed for four years at Newcastle Crown Court for supplying drugs to Martin, although there was no evidence that it was those drugs that killed Mr Dakers.

Hartshorn, of Pembridge, Oxclose, Washington, was arrested after a police investigation found he would supply Ecstasy on credit.

The court heard Martin had been out celebrating a new job and had bought Ecstasy from Hartshorn, who supplied local teenagers as young as 15 with the drug from his car.

Hartshorn denied selling Martin the tablets but a jury took less than two hours at the end of a week-long trial to find him guilty of supplying the teenager and two others.
